How to parameterize the motor
potentiometer …
Parameterize the motor potentiometer as shown below. Use Figure 6-14 as a guide:
• Set the sources for the signals motorized pot UP and motorized pot DOWN in D114
and D115. These signals are used to raise or lower the reference value.
• In D43 enter how the change is to be made. If the value 0 is entered in D43, the
motorized pot reference value is raised or lowered with the ramp from D41 or D42 as
long as the applicable binary signal is active (motorized pot UP, motorized pot DOWN,
Figure 6-14 n, p). When both signals are active, no change is made in the reference
value (Figure 6-14 o).
If you enter a value other than 0 in D43, the reference value is raised or lowered by the
value entered in D43 with each rising edge on the digital inputs (Figure 6-14 Step,
q,r,s). This adjustment uses the ramp entered in D41 or D42. A new change in step
is not executed until the previous step is concluded (Figure 6-14 s).
• The ramps of the motorized pot reference value are parameterized in D41 and D42.

Motor potentiometer ramps
There are two ways to use the ramps of the motor potentiometer reference value based
on the parameter D40 bit7.
• When bit 0 is inactive, D41 is used as the acceleration ramp and D42 as the
deceleration ramp.
• When bit 0 is active, a switch is made between D41 and D42 with a binary signal
(signal source set in D117). In this case D41 and D42 apply to both acceleration and
deceleration.
This makes it possible to approach the range of the motor potentiometer reference
value with a fast ramp. After the switch to the second, lower ramp the motor
potentiometer reference value can be adjusted.
